STANDARD OPERATING PROCEDURE Perawatan Sumur dan Kerja-Ulang Khusus Pengasaman, Fracturing dan Perforasi

1. Pengasaman

Membuat rencana penempatan peralatan untuk masing-masing lokasi dan mereview rencana tsb bersamasama supervisor rig dan perusahaan pengasaman sebelum membawa rig perawatan sumur dan peralatan pengasaman ke lokasi. Memastikan bahwa tata-letak peralatan sesuai dengan panduan penempatan.

Melakukan rapat keselamatan pra-kerja dan mereview program perawatan sumur dengan perusahaan pengasaman dan staf rig perawatan sumur. Mereview Lembaran Data Keamanan Bahan (MSDS) untuk bahan-bahan yang akan ditangani.

Memberitahu Bagian S&E, 24 jam sebelum melakukan pengasaman untuk pe masangan safety shower dan alat pemadam api di lokasi.

Mengikuti Checklist keselamatan kerja dan kontrol kuali tas dari JOB.

Mengikuti panduan dari perusahaan pengasaman untuk penanganan cairan yang mudah berkarat dan mudah terbakar dengan aman.

1.2 Perekahan

Membuat rencana penempatan peralatan untuk masing-masing lokasi dan mereview rencana tsb bersamasama supervisor rig dan perusahaan perekahan sebelum membawa rig perawatan sumur dan peralatan perekahan ke lokasi. Memastikan bahwa tata-letak peralatan sesuai dengan panduan penempatan.

Mengadakan rapat keselamatan pra-kerja dan mereview program perawatan sumur dengan perusahaan perawat sumur dan staf rig rig perawatan sumur. Memberitahu Bagian S&E 24 jam sebelum melakukan pekerjaan untuk memasang safety shower dan alat Manajemen Produksi Hulu

pemadam api ke lokasi.

Mengikuti checklist keselamtan kerja dan pengontrol kualitas JOB.

Mengikuti panduan perusahaan perekahan untuk penanganan cairan yang bisa menimbulkan karat dan mudah terbakar secara aman

Catatan: Lampirkan copy dari SOP ini ke dalam masing-masing program kerja-ulang sumur.

1.3 Perforasi – Tubing Conveyed and Wireline Conveyed

Mengadakan rapat keselamatan pra-kerja dan mereview program perawatan sumur dengan perusahaan perforasi dan staf rig perawatan sumur.

Mengikuti panduan perusahaan perforasi untuk penanganan bahan peledak secara aman

Mereview checklist pekerjaan perusahaan perawatan sumur sebelum da n selama JOB.

Pastikan ketinggian fluida 100 m di atas zona yang akan diperforasi. Lakukan pengecekan kedalaman fluida sebelum memasang packer.

Setelah peledakan TCP gun, gun jangan dilepas dari tubing tanpa diskusi dan persetujuan tertulis dari kepala engineering.
